Sorry, I should have realised this at the time, but I don't think
we can do this after all. The ABI requires us to set up the frame
chain before assigning to the frame pointer.
Sorry again for the bogus suggestion.
Thanks,

OK, thanks Richard :)
But I think I still don't quite understand it, so could the x30 be
shrinked alone when we don't need the frame chain?
Thanks,
Dan.
